Missing Administrator account

Once you have created regular user accounts, the default Administrator account
vanishes from the Welcome screen, which you see when the computer starts up.
Press Ctrl-Alt-Delete twice at the Welcome screen to retrieve the standard logon
dialog. You can log on as Administrator from here. To switch among accounts, just
click the Log Off button on the Start menu. You'll then see the Log Off Windows
dialog box. Click the Switch User button, and you'll be taken to the Welcome screen
where you can select and log on to other accounts.

Speed up the Start Menu

The default speed of the Start Menu is pretty slow, but you can fix that by editing a
Registry Key. Fire up the Registry Editor and navigate to the following key:
HKEY_CURRENT_USER \ Control Panel \ Desktop\Menu Show Delay
By default, the value is 400. Change this to a smaller value, such as 0, to speed it up.
If this doesn't work for some reason, then you might try the following: Navigate to
Display Properties then Appearance then Advanced and turn off the option titled
Show menu shadow. You will get much better overall performance.

  Or

Close Multiple Windows : Note works in all versions of Windows

If you just opened a number of separate, related windows (a folder inside a folder,
and so on), there's an easier way to close them all than one-at-a-time. Hold down
the Shift key as you click the X caption button in the upper-right corner of the last
window opened. Doing so closes that window and all windows that came before it.
